The Cooperative Phonograph uses Thomas Edison's analog audio technology from 1877 in an all-new experience, where the mechanical generation of sound is perceived to be magic by recent generations of "digital natives".
Users generate sound in the same way loudspeakers do.
Users hold a plastic card against stainless steel surfaces textured with sound waves.
One person spins the large disc to maintain the rotation, while another person holds the card against the tracks, generating the audio experience.
This shared-control interface encourages users to cooperate and engage with each other.
The Cooperative Phonograph provides an experience that is tactile, visual and auditory.
While it is delightfully entertaining, it is also stimulating curiosity and directly illustrating the essential physics of sound, and demonstrates the earliest method that sound could be reproduced from a recording.
